Organic Statute of Macau

The Organic Statute of Macau (Portuguese: Estatuto Orgânico de Macau, EOM; Chinese: 澳門組織章程) was a Portuguese organic law (Law No. 1/76) that provided for government in Portuguese Macau. Approved on 17 February 1976, the Portuguese legislation also reclassified Macau as a "Chinese territory under Portuguese administration" (território chinês sob administração portuguesa).

The promulgation of the EOM was aimed at creating a new and more autonomous political model. It was the most important piece of local legislation defining the functions of Macau's main political, legal and administrative bodies and the general operation of the Territory. As a result of the approval of the EOM, a political novelty for Macau was born in 1976: the major remodelling and partial democratization of the Legislative Assembly of Macau to exercise the legislative function of the city.

The Organic Statute of Macau replaces the Political-Administrative Statute of the province of Macau, which, approved in 1963, enshrined in Macau the old colonial model based on the colonialist and authoritarian ideology of the Estado Novo, overthrown precisely in the Carnation Revolution of 1974.

The Organic Statute of Macau, in accordance with the Constitution of the Portuguese Republic, was amended successively by Law No. 53/79 of Macau, of September 14, 1979; Law No. 13/90 of Macau, of May 10, 1990; and Law No. 23-A/96 of Macau, of July 29, 1996.

On December 20, 1999, the organic statute ceased to have effect following the implementation of the Macau Basic Law, as the territory became a special administrative region of the People's Republic of China and ceased to be a territory under Portuguese administration.
